Description
Technical field
The present invention relates to a kind of solid-liquid inversion of phases brine concentration methods.
Background technique
Production field can generate a large amount of brine wastes, and such direct discharging of waste water is polluted the environment and destroyed.Such as contain
Salt waste water seepage flow enters in soil system, and geobiont, plant can be made dead due to dehydration, cause watt of soil ecosystem
Solution, if unprocessed direct emission, very big pressure will be brought to water body environment, accelerates the eutrophication process of rivers and lakes.
In short supply with water resource with the development of industry, the production waste strength of saliferous caused by some industrial trades is higher and higher, row
High-volume increasing, brought environmental pressure is also increasing.Therefore, the research of saliferous technology for treating industrial waste water is compeled
The eyebrows and eyelashes.The processing of brine waste at present generallys use minimizing and adds evaporating and concentrating process, and the degree of minimizing determines waste water
The operating cost of processing.Technology used by the minimizing of brine waste has membrane separation technique, ion exchange technique, electricity at present
Solution technology and these technologies are applied in combination, but since the problems such as treatment process is also easy to produce fouling, corrosion causes equipment to be lost
Effect, meanwhile, minimizing degree (cocnentration factor) is limited, and operating cost is very high, and enterprise is difficult to bear.
Salt water provides new approach for brine concentration with the solid-liquid phase relation of temperature.
As seen from Figure 1, Fig. 1 be typical salt-water phase figure, the eutectic point concentration of most of salt be all it is relatively high,
If the concentration of salt water is in this position A.When temperature reduces, when salt water reaches B point from A, since brine strength is dense lower than eutectic
Degree, therefore pure ice can be first precipitated in solution, to increase the concentration for not solidifying salt in solution.When temperature reaches D point, due to a large amount of
Ice is precipitated, the concentration of solution reaches eutectic concentration just at this time, and at this moment water and salt start to be precipitated simultaneously.Phase region where C point is
Ice formation is analysed, the concentration of salt water can only be completed in this region, the attainable highest brine strength of institute is no more than eutectic point
Concentration.
Above-mentioned principle has been used for the proportion of ice storage, freezing and cooling medium, the purification of inorganic salts etc., but is used for
There is not been reported for salt water serialization concentration.
For sodium chloride solution, current method is usually concentrated into 6% or so, and highest 12% is concentrated in multistage, but disposable
Investment and operating cost are all very high；And use analysis ice method that can be concentrated into 20% or so (eutectic point concentration 23.2%), and invest and
Operating cost is but very cheap.
Summary of the invention
The purpose of the present invention is to provide a kind of simple production process, brine concentration treatment process be not likely to produce fouling,
The cost of the problems such as corrosion, the long service life of equipment, brine concentration are low, high-efficient, energy-saving effect solid liquid phase very outstanding
